When I convert my java class into jsonobject it reshuffles the order of class members

Question

I am using objectmapper to convert the class into json. Following is the code:

JSONParser parser = new JSONParser();
ObjectMapper mapper = new ObjectMapper();
String obj = mapper.writeValueAsString(myClass);
JSONObject jsonObject = (JSONObject)parser.perse(obj);

now line number 4 where I get the jsobObject reshuffles the order of class member. See the attached image, before it converting to jsonobject "authorisation" was first element then signatries. But at line 4 it becomes 2nd ..... why ? I want order to be preserved, that is the requirement of my project. Please help !

Answer 1

You can configure the ordering this way :

@JsonPropertyOrder({ "authorisation", "signatoryDetails", "requestedLimits" })
public class MyClass { ... }
